Hello 113 Students,

I hope you all are enjoying the snow day and gearing up for your mineral quiz next week. If you did not see the videos on minerals I posted from youtube check out the last post. Today I want to post a lecture regarding igneous rocks. Remember that all rocks are composed of different types of minerals, and this is why learning the minerals will help you in studying for igneous rocks. Here is a lecture on igneous rocks that should prepare you for class tomorrow.
